Not necessarily faster, but more easy for sure. There's plenty of stories of proficient abacus using accountants being faster than those using calculators. Those days are gone now though because a calculator is just so much easier to pick up.
While buying an EV is a greener choice than buying an ICE, a better option still is to use the vehicle you already have for as long as reasonable. This also overlooks the fact that EVs are prohibitively expensive for the vast majority of the population. It isn't the case that people aren't buying them because of preference. Nearly everyone would buy a car that's cheaper to run and maintain if they could afford it.
That's absolutely untrue. The majority of the environmental damage is from the ongoing use of it, not from production.
Every time you fill up on 20 gallons of gas, that is 400 pounds of CO2 that will be dumped into the air.
Used EVs are apparently very cheap. Most new cars are prohibitively expensive, the average new car cost is something like $50k now in the US. If anybody is concerned about cost of new cars, they are buying used anyway.
It is true though, in some cases. The embodied carbon of a Rivian for example is never paid back by operations. So you do have to exercise good judgement in which EV you choose. The category doesn't always win.
In my case I already own a hybrid that I only drive 2000 mi/yr and there is not yet an EV that I could buy with so little embodied carbon that it would make sense to do so. At the rate China is decarbonizing, presumably the embodied carbon of their EVs will soon be minimal, but not yet.
Thanks for linking that Rivian document later, but I think it doesn't support this claim. I'll stick with it's weird 155,000 mile lifetime for the comparison.
Rivian: 60,140 kg carbon per lifetime.
F150, at 20mpg: 78,740 kg carbon, for fuel alone.
So even ignoring the embodied carbon in an ICE vehicle, and paying comparatively high embodied CO2 cost of a new Rivian, it's better to switch immediately, (if CO2 were the sole concern, which it never is.)
An F150 is also a poor choice, so I don't think of it as a point of comparison. As an approximation, the mass of any object is related to its embodied carbon, so smaller vehicles embody less of it. Massive vehicles embody current emissions and that is worth considering.
That only works if you take it at face value that buying either of them is a rational transportation choice, which I reject. Even if I accept the people need a weird truck-shaped thing with a useless 4.5-foot bed, a far better choice on emissions grounds would be the Ford Maverick XL, which has a battery 1% as massive as the R1T's battery, yet this tiny battery cuts the per-mile GHG emissions in half. The embodied carbon payback distance of an R1T versus a Maverick XL is over 100,000 miles.
My kid races mountain bikes so I have become extremely familiar with Rivian (and Cybertruck) MTB Dad, and I think they are a joke. With only a little planning I can get three bikes and three riders in a Honda Insight, while R1T Dad needs an optional accessory to get even one bike in the bed. People choosing these things are, 99% of the time, not behaving rationally. They are buying luxury goods that they believe signal their environmental credentials.
> The embodied carbon of a Rivian for example is never paid back by operations
Really? I could imagine it being significantly longer than an average EV, but never? Regardless of driving pattern? Got a link or can you show your math?
To add to this, almost nobody statistically keeps their vehicle very long. People keeping a car for 20-30 years is extremely rare.
The median length of car ownership is something like 7 years. Even if you are switching between used cars, most people are switching vehicles at some point.
From what I understand even considering battery mining and using dirty electrical generation, you’re still at breakeven within a couple years of driving with an EV.
Yeah lithium mining is bad, but don’t forget that oil is also extracted and “mine.” And your gas car uses a LOT of it.
I wouldn’t think too much about then average new car cost of $50k. That average is skewed by:
1. Expensive new car purchases (average != median)
2. Lower income people don’t buy new cars at all.
Still, some of the best new car deals are EVs because dealers can’t get rid of them due to the sudden expiration of federal incentives. Plus the used ones depreciate like crazy despite having better maintenance and lower miles. The lease deals you might get on an Ioniq are insane, good luck getting a gas car lease with that kind of value.
Let’s also not forget that the majority of housing units in the USA are single family homes where charging at home is likely to be an option.
The EU average passenger car fleet age is 12.5 years.
> From what I understand even considering battery mining and using dirty electrical generation, you’re still at breakeven within a couple years of driving with an EV.
Only when compared to buying a new ICE, as it takes 1-2 years average mileage in the US and 2-4 years in the EU for a new EV to reach emissions parity with a new ICE. It takes well over a decade in the EU for a new EV to recover it's production emissions va driving an existing used ICE. It's never environmentally friendly to scrap an ICE for a new EV.
The average length of ownership is a pretty warped statistic, though. It is dependent on when in the car's life cycle someone buys it. At one end of the market are new car buyers who keep them longer than average, at the other end are people who constantly buy end-of-life junkers for $500.
Bike > walk == public transit > used EV > new EV > used ICE > new ICE
That's pretty much the order of "greenness" in personal transport.
New EVs will pay off their added carbon footprint in roughly 1 or 2 years in most locations. The ultimate determining factor of how fast that is the energy mix of your local power generation.
The only time it'd probably be better to continue using an ICE is if that ICE is a moped or you live in West Virginia and drive a hybrid. For pretty much all other vehicle choices, switching to an EV will be greener.
New EV vs used ICE will depend on how much you drive and in what conditions. I would guess what I do (in the UK) is uncommon in the US but it must be possible but working from home plus living in a town rather than a city means I only do low single digit thousands of miles a year and that almost entirely on clear roads.
People in much of the UK commute by public transport and use their cars lightly (e.g. for shopping on the weekend, trips, etc).
Biking has an energy efficiency of around 99%. Very little of the effort you put into biking ends up as waste heat. Walking, on the other hand, has a much lower energy efficiency. You are putting much more effort overcoming and generating friction as you move your legs. You are also doing it for a longer period of time since you are going slower.
It's one of my favorite counterintuitive facts.
> I would guess what I do (in the UK) is uncommon in the US
And that's for sure. In almost every US city if you want to do anything, you are driving. Where I'm at, everything is at least 10mi from my home. That racks up the miles pretty quickly.
Walking covers most of my journeys for which a bike would work. I am not going to bike a hundred mile, or even 15 and back. Nor is it practical to bike to the supermarket. On the other hand its easy to walk a few minutes to the local shops and pubs.
Transportation and exercise are linked. Walking kills two birds with one stone.
This type of thinking is flawed. Me buying a new EV does not take my old ICE out of circulation, it just puts it in the hands of someone else. Buying less, whether that's cars or anything else, is the baseline to aim for.
From an old forum post in 2013, the best I can find is about 15 tons.
I suspect it's much lower than that number now-a-days. Primarily because the energy going into batteries production will both use less power and likely comes from greener power sources.
If nissan is to be believed, since then they've cut the CO2 emissions from production by 40%. So maybe in the range of 9T?
I kept my last car for almost 20 years for that reason, but parts were rusting off - the fuel tank fell off was what made me give up. At this point that car is scrap and I am in a newer car that is made no matter what, so that co2 is a given.
The sunk cost fallacy applies not only to dollars, but also to any quantitative phenomenon. The important thing to evaluate is the cost going forward. When you look at the cost of that new Nissan Leaf, you need to amortize the initial carbon cost over the rest of its lifetime, not just the few years you have it!
Shoes have a lower environmental impact and cost than than steel, plastic, rubber tyres (which AFAIK use at least some synthetic rubber made from oil), etc. Walking does not use fuel so efficiency is not really relevant. It requires less physical extortion so is more efficient that way, but another way to phrase that is that it is less exercise.
Bikes require very little steel and the rubber tires end up lasting longer (typically) than the shoes you do.
> Walking does not use fuel so efficiency is not really relevant.
Ah, it is. You eat food, that's fuel. It's the major source of CO2 for both activities. Now, it can be insignificant. If the only food you eat is like oatmeal and beans that you grow yourself, then yeah it's going to have a non-existent impact.
However, if you have any sort of meat or imported foods, that CO2 budget can go up pretty quickly.
The actual energy for making the steel for a bike, which will outlast your children, isn't significant.
> Ah, it is. You eat food, that's fuel. It's the major source of CO2 for both activities.
That implies all exercise is a bad thing. i think you will find very few people are sufficiently keen to reduce CO2 that they will deliberately get less exercise and damage their health. I am certainly not doing that. At the moment I am trying to get more exercise.
> Bikes require very little steel
Compared to a car, certainly. Compared to shoes, an awful lot.
> a bike, which will outlast your children
The typical life span of a bike seems to be about five and ten year years. I really hope my kids last a reasonable multiple of the top end! The level of sales of cycles in the UK (well over 1 million a year) vs the number of people who cycle at least once a week (less seven million) implies a life of about five years. About half of that is leisure cyclists so not really comparable to people using transport to get somewhere.
Leisure cyclists want to get more exercise so by your argument about that being a bad thing they (and therefore half of all UK cyclists) are actively harmful.
> another way to phrase that is that it is less exercise
Biking is less demanding on some parts of the body that only can take so much stress. So you can push other parts more if that makes sense: top cyclists can do 400-600 W sustained or 1-2 kW in short sprints. That's not less exercise, that's several times more than a walker or runner can do. So in the same time as walking you can either be faster at your destination and save time and/or energy, or go further while spending the same or less energy, or output more energy. The choice is yours.
Anyway, from the CO2 perspective, biking vs walking is splitting hairs really.
> Top cyclists are doing it as a sport, not as a means of transport.
Well you were mentioning exercise, so I reacted to that. The point is everyone biking as exercise can push more watts than when walking, if they want to.
Those must be US estimates involving huge mileage, because - taking your existing ICE car's production emissions as an already sunk cost - replacing an existing ICE with a new EV would over a decade of driving the average EU mileage (~10k km) before reaching emissions parity.
It takes 2-4 years of that mileage alone for a new EV to reach lifetime emissions parity with a new ICE in the EU (which I know is longer than the US due to the vast differences in average emissions per vehicle between the two continents).
For most of the world, the GP is correct. Driving whatever car you have will always be more environmentally friendly than buying a new EV. Reduce and reuse are environmental cornerstones for a reason.
People keep their cars for longer than 2 to 4 years and an EV sold in 2 to 4 years will likely be driven by someone else.
Which is why I put a used EV as being better for the environment vs a new one.
But both will be better for the environment in their lifetime than keeping a used ICE on the road.
It's more economical to keep your current car until it starts seeing major mechanical issues. However, environmentally an EV will (almost) always beat an ICE, the sooner you get one the better. Especially in a place like the EU where you can get even more environmentally friendly EVs due to the lower amounts of driving. You can, for example, grab the BYD seagull which has a 30kWh battery pack. That alone significantly reduces the new EV environmental impact beyond what some of the older numbers would have shown.
> However, environmentally an EV will (almost) always beat an ICE, the sooner you get one the better. Especially in a place like the EU where you can get even more environmentally friendly EVs due to the lower amounts of driving.
This is simply not true. A new EV will not reach emissions parity with a used ICE car in its average useful lifetime (12.5 years).
This isn't close or controversial, so I wonder what the basis for your mistaken belief otherwise is? Not even EV companies make this claim.
The payoff period for an EV is anywhere from 15,000 to 25,000mi. The moment any EV crosses that threshold, it becomes better for the environment than the ICE vehicle that you'd otherwise buy.
If your used ICE vehicle has 15 to 25,000mi in it, then yeah, replacing it with an EV today is the better choice. It's more a matter of when it will be the better choice.
This is only not true if you have very low yearly milages or a particularly efficient ICE. Which, maybe you do.
> The payoff period for an EV is anywhere from 15,000 to 25,000mi. The moment any EV crosses that threshold, it becomes better for the environment than the ICE vehicle that you'd otherwise buy.
That's the payoff period for the carbon differential between a new EV and a new ICE, not a new EV and your existing ICE, where the carbon cost of production is already sunk. Hence why the GP commented that keeping your ICE is environmentally better than buying a new EV.
Also note that 15-25k miles is 24-40k km, or 2.4-4 years of the average annual mileage in the EU. That's to break even with a new ICE. To break even with a second hand ICE, it's on the order or 15-20 years, or effectively longer than the useful life of the EV.
> If your used ICE vehicle has 15 to 25,000mi in it, then yeah, replacing it with an EV today is the better choice. It's more a matter of when it will be the better choice.
This claim is simply false. There is no point in the lifetime of a used ICE where replacing it with a new EV will result in reduce overall emissions.
From the ICCT, ironically under the subtitle "Addressing misuse of data in the EV debate":
> One common claim is that electric vehicles have higher emissions associated with battery manufacturing. While manufacturing emissions for battery electric cars are roughly 40% higher than for gasoline cars, the ICCT’s research shows that this initial “emissions debt” is typically offset after around 17,000 kilometers of driving, usually within the first one to two years of use in Europe.
The emissions debt is relative to a new ICE.
In cradle-to-grave emissions, electric cars are much lower than ICE cars in lifetime carbon footprint, often 50% lower.
That doesn't change the fact the replacing a used ICE with a new EV will result in increased overall emissions and increase the net carbon footprint.
> I'd love to see a source that says otherwise. I think you have a bad source for the CO2 emissions of new EV production.
This is a completely uncontroversial fact and no environmental or governmental bodies make the claim which you are putting forward, so I'd rather like to see your sources.
So I'm looking at the given graphs in your linked article and I just don't see how you are coming up with the 12 and 20 year timeframes for payback of EVs.
Just fuzzy eyeballing (I don't see the actual numbers for the manufacturing estimated CO2, just the graph), it looks like ~10% of the lifetime emissions for a new ICE come from manufacturing. That would put the the new EV payback vs used ICE at 4 or 5 years.
At that point, it just sort of depends on how long you hold onto your ICE for.
All the oil and gas is killing the planet. Even the gas fumes are killing you when you fill up. The sooner the better. There are lots of low cost EVs out there, especially when you factor in there’s no maintenance.
The maintenance factor seems to often be overlooked. The amount of time I've put into EV maintenance in the last decade is about the same as I've put into my two ICE cars, but I drive them 1/10th as much. It's really, really nice, and I don't think dealer service departments are ready for a massive switch to EV.
Mostly agree but own an EV. "No" maintenance is an exaggeration and it's not necessary to make your point.
My car's first set of tires were very bald at 25,000 miles. That's not unusual on new cars in general as they seem to come from the factory with low longevity tires, but it's still quite a short tire life.
Yes anything in a gasoline engine is gone, and brakes get less use.
When discussing vehicles it’s common to separate “wear” items and “maintenance” items. Brake pads and tires are “wear” items. Replacing your engine oil every 5-7000 miles is “maintenance”.
> a better option still is to use the vehicle you already have for as long as reasonable
I've gone back and forth on this. When you buy an EV your old ICE vehicle is not destroyed, it continues it's lifecycle when it goes to someone else. Moreover, there's value in sending a market signal in buying an EV, which is important at this stage of transition.
Maybe the argument is about average age of the road fleet? That a used ICE vehicle should be replaced with a used EV?
Plenty of people that can afford them and that would likely benefit are not buying them because of preference.
In many cases, this is rational. Yeah, a used Model 3 with a great rate plan is probably worth it as a commuter, but what if you are an outlier? Even a low battery failure rate can be a risk, and extended warranties are expensive.
But also, some of it is irrational, as the FB comments effectively feed many false fear driven narratives.
Just because written communication works well for you doesn't mean that it works for others nor that it's the best way to communicate about everything. There's a place and time for both. For example with documentation, it's nice to have accurate and well thought out docs so you can search and read through it, but oftentimes it's faster if your teammate just tells you what bit you need. Meetings are the same way. We've all been in meetings that could've been an email, but that doesn't mean every meeting can be an email.
I don't think this is a charitable interpretation. As a business, you need to be able to backfill positions or hire more when the need arises. If you use a language that's very commonly used, it's a lot easier to hire. There isn't anything sinister to that, it's simply reasonable.
There was a post, I think on the Uber engineering blog, that stuck with me. It essentially boiled down to: it's easier to change the tech stack than the hiring pool, and talked about deliberately setting something up that was technically less optimal but easier to hire for
Corollary: it's perhaps easier to throw money at fancier hardware to improve performance, than the alternatives

Literally every country worldwide does this. The question is simply to what extent and to what countries. The whole difference between being a native an an alien is the rights you get. It's not a human right to be able to freely go into any country you please.
> The whole difference between being a native an an alien is the rights you get. It's not a human right to be able to freely go into any country you please.
The first step for genocide is to dehumanize people.
They're not humans, they're aliens. Therefore it's fine if we treat them as filth and throw them away (or gas them).
It's interesting you got downvoted, perhaps for the sentence
> The whole difference between being a native an an alien is the rights you get.
A knee jerk and uncharitable reading might make this look bad, but it does require an uncharitable reading. It is clear what you mean.
However, the claim
> It's not a human right to be able to freely go into any country you please.
is not false. The idea that open borders are a good thing is a very odd idea. It seems to grow out of a hyperindividualistic and global capitalist/consumerist culture and mindset that doesn't recognize the reality of societies and cultures. Either that, or it is a rationalization of one's own very domestic and particular choices, for example. In any case, uncontrolled migration is well-understood (and rather obviously!) as something damaging to any society and any culture. In hyperindividualistic countries, this is perhaps less appreciated, because there isn't really an ethnos or cohesive culture or society. In the US, for example, corporate consumerism dominates what passes as "culture" (certainly pop culture), and the culture's liberal individualism is hostile to the formation and persistence of a robust common good as well as a recognition of what constitutes an authentic common good. It is reduced mostly to economic factors, hence globalist capitalism. So, in the extreme, if there are no societies, only atoms and the void, then who cares how to atoms go?
The other problem is that public discourse operates almost entirely within the confines of the false dichotomy of jingoist nationalism on the one hand and hyperindividualist globalism on the other (with the respective variants, like the socialist). There is little recognition of so-called postliberal positions, at least some of which draw on the robust traditional understanding of the common good and the human person, one that both jingoist nationalism and hyperindividualist globalism contradict. When postliberalism is mentioned, it is often smeared with false characterization or falsely lumped in with nihilistic positions like the Yarvin variety...which is not traditional!
Given the ongoing collapse of the liberal order - a process that will take time - these postliberal positions will need to be examined carefully if we are to avoid the hideous options dominating the public square today.
Pardon me if I’m misreading it but this sounds like disinformation. No examples in your example, a lot of abstract reasoning unmoored from facts.
>uncontrolled migration is well-understood (and rather obviously!) as something damaging to any society and any culture.
The US was built on unrestricted immigration for a long time. Was that destructive? I guess so if you count native Americans but not to the nation of USA.
Capitalism wants closed borders to labor and open borders to capital. Thats how they can squeeze labor costs while maximizing profits. The US is highly individualistic but wants closed borders so how does your reasoning align with the news?
